Hi,

we enable or disable panel with a condition on a null value.

Files attached :
- liste.mrt : report.
- data.json : data used to produce report.
- Line_type_1.png : expression to filter type 1.
- Line_type_2.png : expression to filter type 2.
- export.png : incorrect pdf export

lines with order 1, 3 and 4 should have "CASSOULET CREOLE AU COCO", "BOITE TRANSLUCIDE PP 37,5CL /500" and "ARABIS caucasica" captions. This the expression in Line_type_1.png who contains artgrilleval_lib1 == null
lines whith order 5 should have "ENSEIGNE DE TROTTOIR DIBOND SUR PIED RES" caption. This the expression in Line_type_2.png who contains artgrilleval_lib1 != null

I think expression are incorrect but i don't understand where is my error.
I've unchecked "Convert nulls" on report component.

Thanks,

Fabien

Hello,

Your column is a string, please check the following expressions:
{lignepiece.lignepiece_lib == ""}

Thank you.

Hi,

It works.
it is important to know that the test should be done with double quotes and not single quotes.

Thanks,

Fabien.

Hello,

You are welcome.

Hi rice purity test
It seems to be a technical issue related to enabling or disabling a panel based on a condition involving null values. The user is experiencing trouble with expressions in Line_type_1.png and Line_type_2.png but is unsure where the error lies, despite unchecking "Convert nulls" on the report component.
